Rhino 450 Dynatek CDI upgrade:
I just swapped out my stock Rhino CDI for this Dynatek 450
CDI. It was easy to install and made the Rhino accelerate slightly
faster. It seemed like it sounds better now also. The top speed
limiter was removed making my Rhino have a top speed of 41
MPH. It could hit 37 MPH before with my 26" tires. The
annoying popping at top speed is gone and it revs all the way
up to 9000 RPMs over the stock 7400 RPMs . I expected it to
go way faster with this $200 upgrade but I got a 3-5 MPH increase
and some better acceleration on a bone stock motor. I just
raced another Rhino 450 on the street and beat him both times
by 3 or 4 Rhino lengths. Before we were side by side every
time we raced. I recommend keeping your stock CDI just in case
the Dynatek malfunctions or doesn't mix well with future modifications.
I also heard if you get an exhaust with this CDI your 450 will
be as fast as a stock 660. Hmmm.

There is a CDI available for the 660, I have not heard of any
for the New Rhino 700 with fuel injection yet.
Was the Dynatek CDI worth $200 bucks? If you think 3-5 MPH
is worth $200 bucks then get it. I did.
Update: Tested the Dragonfire
Racing Rhino CDI on a stock Rhino 450 and
the top speed was about 38-39 MPH. The low end
was real quick. When I gunned it, it spun em'.
No race yet, but soon.
Update: Hit 42 MPH with the Dynatek CDI
in my Rhino 450. If you have a CDI you will pull
away from stock Rhinos when they hit top speed.
